Description

Technical Field

[0001] This application relates to the field of electronic device technology, and in particular to an electrical connector that can electrically connect multiple conductive terminals. Background Technology

[0002] In recent years, electrical connectors have been widely used in various electronic devices. However, due to the special needs and development of electronic devices, multiple conductive terminals on electrical connectors may need to be electrically connected to each other. For example, electrical connectors are prone to generating crosstalk interference when transmitting high-speed signals, which causes interference attenuation in the transmission of high-speed signals. Therefore, multiple conductive terminals (such as grounding terminals) on electrical connectors may need to be electrically connected to suppress the generation of crosstalk interference.

That is, the left front end overlap structure 133, the right front end overlap structure 134, the left rear end overlap structure 135, and the right rear end overlap structure 136 of the main-side common ground component are electrically connected. Therefore, the main-side common ground component 13 allows the main-side left ground circuit and the main-side right ground circuit to share a common ground to form a main-side common ground circuit, thereby transmitting a ground signal and meeting the usage requirements of the electrical connector 1.

Therefore, the secondary common ground component 15 allows the secondary left ground circuit and the secondary right ground circuit to share a common ground to form a secondary common ground circuit, thereby transmitting a ground signal and meeting the usage requirements of the electrical connector 1.

[0159] At Figures 1 to 4In the embodiment shown, the insulating body assembly 11 is joined with the main side terminal assembly 12, the main side ground assembly 13, the secondary side terminal assembly 14 and the secondary side ground assembly 15 to assemble the insulating body assembly 11, the main side terminal assembly 12, the main side ground assembly 13, the secondary side terminal assembly 14 and the secondary side ground assembly 15 into an electrical connector assembly component E.

[0160] In addition, Figures 37 to 38 In the embodiment shown, the front and rear ends of the electrical connector assembly component E have a main front circuit board E11, a main rear circuit board E12, a secondary front circuit board E21, and a secondary rear circuit board E22, respectively.

[0167] In addition, Figure 37 In the embodiment shown, the exposed lengths of the secondary left ground terminal front-end overlap structure 1411 and the secondary right ground terminal front-end overlap structure 1421 on the secondary front circuit board E21 are longer than the exposed lengths of the secondary left signal terminal front-end overlap structure 1431 and the secondary right signal terminal front-end overlap structure 1441 on the secondary front circuit board E21. This allows the secondary left ground terminal 141 and the secondary right ground terminal 142 to overlap and connect with the secondary left signal terminal 143 and the secondary right signal terminal 144 earlier than the secondary left signal terminal 143 and the secondary right signal terminal 144, ensuring that the electrical characteristics of the electrical connector 1 meet expectations and can be widely used in various electronic devices.

[0169] In addition, Figures 7 to 10 In the illustrated embodiment, the electrical connector 1 has a grounding assembly 16, which is, for example, a conductive plastic body, and electrically connects the primary grounding assembly 13 and the secondary grounding assembly 15, making the primary grounding circuit and the secondary grounding circuit share a common ground. In the above embodiment, the grounding assembly 16 has a primary grounding assembly grounding terminal shield 161 and a secondary grounding assembly grounding terminal shield 162.
